Need help remapping key combos in Karabiner Elements

[xxhellfirexx]

I am not sure what I am doing wrong, but I am unable to do a double tap of left shift+right shift to give me a backspace, yet alone a option+backspace. Here is what I have so far:

I took snippets from
https://pqrs.org/osx/karabiner/json.htm ... on-control
and
https://pqrs.org/osx/karabiner/json.htm ... ard-delete

Any help will be much appreciated.

Finally got it figured out. I am posting it here in case anyone wants to use it.

Both shift = backspace. Both shift 2x = option + backspace (delete word).

Now if only this can be done with Soarer's converter. I haven't been able to figure that out.
